I have a b18a1 engine and want to know what the best head swap would be. Could I get a b16a2 swap or is head to small. Also if i were to get the head swap of a b16a2 would my rpm's go any higher?If yes how high would they go? The b18a1 has no mods at all. thanks,

Omar

No, considering the ECU controls the fuel cutoff . . .

Actually it's called an Ls/Vtec! You would have to get an Ls/Vtec kit, a timing belt(use GSR), a waterpump(use GSR), a chipped ECU(GSR would work but not that good), vtec wired(if it isn't already), etc...(if the head isn't complete then you'll need more stuff. (And yes you don't have to use the GSR stuff but it makes it simple if you do it that way)

The head isn't too small it will work with the above mentioned stuff. You can rev them a little higher but I wouldn't go over 8,000(some people will tell you more and some will say less rpms) if you don't have ARP rod bolts and such.

Read up on Ls/Vtec's and find a little more info before you decide what you want. to do.

It will run like **** if you just put the head on(with the kit and etc...) and you don't run the right ECU, dizzy, and don't get it wired(if it isn't already)!

I wouldn't even do 8000 if you don't upgrade the rod bolts. There is no point at all in building an LS-VTEC engine unless you do the rod bolts. All it takes is one spun rod bearing to ruin a crank . . .

 

Nobody mentioning the intake valve reliefs on the ls pistons being too small? Or am I wrong on this, and this just pertains to the b20 piston? Now I have confused myself and am very curious.

 

No you don't have to cut valve reliefs in a stock Ls/Vtec...I guess it's just a CRVtec thing(never heard of it on them...but I've never actually seen one).
